Ben- I think what you will likely have to do is plug in a USB mass store device into the system that you are setting policy on and look under the USB Controllers within the device browser. The one thing I'm not sure about is how GP Preferences stores those device definitions. If they are stored by device class (meaning all USB mass storage devices) or by a specific ID (meaning that it only applies to the one you've plugged in). I think its probably worth testing that.

However I'm having difficulty trying to determine where I would go to prevent the users from plugging in USB hard drives and flash drives? If I could just get this one last piece to work, then this would satisfy the customer. Any suggestions? ~Ben From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Darren Mar-Elia Sent: Tuesday, July 08, 2008 10:28 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Re: Prevent access to USB disks and portable media drives Yes, but perfectly accessible from those lower-level platforms.

I'm not familiar with them, or I've been completely ignorant of them in Windows Server 2003 unfortunately. This is indeed a Windows Server 2003 R2 domain with Windows XP clients. ~Ben From: gptalk-bounce@xxxxxxxxxxxxx [mailto:gptalk-bounce@xxxxxxxxxxxxx] On Behalf Of Darren Mar-Elia Sent: Tuesday, July 08, 2008 10:22 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] Re: Prevent access to USB disks and portable media drives Ben- Assuming these are not Vista-based systems (Vista provides this kind of restriction capability out of the box in GP) then you can use GP Preferences to restrict access to storage devices like these.

I found a great article with a pre-built ADM template, however it is a computer based policy, and I require a user based policy. Is anyone aware of a way to accomplish these using user-based policies? Thanks, ~Ben
